manual abstract
Proper installation, maintenance and operation procedures must be observed. The instructions in the instruction manuals must be followed. Inspections should be made as necessary to assure safe operation under prevailing conditions. Proper guards and other suitable safety devices or procedures as may be desirable or as may be specified in safety codes should be provided, and are neither provided by Baldor Electric Company Automaton nor are the responsibility of Baldor Electric Company. This unit and its associated equipment must be installed, adjusted and maintained by qualified personnel who are familiar with the construction and operation of all equipment in the system and the potential hazards involved. When risk to persons or property may be involved, a holding device must be an integral part of the driven equipment beyond the speed reducer output shaft. Baldor Electric Company Headquarters P.O.

Standard NEMA-B motors with RPM base speeds of 1750, 1160 or 860 are commonly used with a FLEXIDYNE, yet other available power sources may be used with the FLEXIDYNE. The dry "fluid" in the FLEXIDYNE is heat treated steel shot. A measured amount, referred to as flow charge, is added into a housing which has been keyed to the motor shaft. When the motor is started, centrifugal force throws the flow charge to the perimeter of the housing, packs it between the housing and the rotor which in turn transmits power to the load. After the starting period of slippage between housing and rotor the two become locked together and achieve full load speed, operating without slip and with 100% efficiency. Consequently, the motor accelerates instantly to base speed, while the load starts gradually and smoothly. INSTALLATION Method 1: Install coupling flange on motor shaft and drive housing mechanism on driven shaft in accordance with the instructions packaged with the TAPER-LOCK® bushings (Manual #499645). Note: The coupling flange must be mounted on motor shaft (not driven shaft) to allow proper operation of the FLEXIDYNE. Shaft ends must not protrude beyond bushing ends. Install coupling disc over pins on drive housing mechanism. Position motor and driven unit so that spacer buttons on coupling flange just contact the drive housing and coupling flange (Reference dimension "A" on page 5). Method 2: If motor and driven unit are to be positioned before mounting FLEXIDYNE, shaft ends should be spaced apart by dimension "B" on page 5. Slide bushing and coupling flange onto motor shaft. Install coupling disc over pins on drive housing mechanism. Install drive housing mechanism on driven shaft and coupling flange on motor shaft per instructions packed with the TAPER-LOCK bushings, so that the spacer buttons on the coupling disc just contact the drive housing and coupling flange (Reference dimension "A" on page 5). Make certain that shaft ends do not protrude beyond bushing ends. For longest FLEXIDYNE coupling life, it is always desirable to align coupling as accurately as possible at initial installation. Check alignment by laying a straight edge across the coupling flange and drive housing at several points around the circumference. FLEXIDYNE Size 9C 11C Dimension “A” 7/8 11/8 Dimension “B” 51/8 61/8 START-UP 1. Remove one of the filler plugs and install . the proper amount of flow charge specified in Table 1. Replace and tighten filler plug, making sure that no flow charge is trapped in the threads. Remove other filler plug and install the remaining . of specified amount of flow charge repeating the same procedure. Tighten filler plug to 200 inch-pounds torque. 2. Attach AC ammeter (conventional clamp-on or equivalent) to one line of the AC motor. Set range to cover 200% of motor nameplate current. 3. Note maximum allowable acceleration time for FLEXIDYNE as stated in Tables 1 and 2. Note: Table 2 lists starting time capacity for starting cycles occurring more than once every 2 hours. 4. Push start button. Observe motor current during load acceleration and number of seconds required to reach full speed (Fig. 2). Increase amount of flow charge if: A. Acceleration time reaches maximum allowable before load is up to speed. Turn off power immediately if this time is reached. B. Acceleration amper...
